Degree, cutter chuck applicatory is taper sleeve type cutter chuck, which is characterized in that the air-floating main shaft Pneumatic tool-changing apparatus has rotation
Turn a work take offence chamber and rotation-straight line conversion assembly；There is movable plate, the movable plate is in external gas in the rotary moveable air cavity
It can make the rotary motion of positive and negative both direction under the action of pressure；The movable plate connects the rotation-straight line conversion assembly and drives
Move the rotary body rotation in the rotation-straight line conversion assembly；The rotation-straight line conversion assembly is by the rotation from movable plate
The output that is in line is converted in input, and straight line output is transferred to the cutter chuck by parts moving linearly, realizes knife
Has the transformation of collet tightness.
In certain embodiments, the rotary moveable air cavity is by seal chamber, central axis, movable plate, fixed plate, the first gas
Mouth, the second port composition；The seal chamber is isolated into the discontinuous cavity in direction of rotation by the fixed plate；The movable plate
Around the center axis rotation；The first port or the second port are spaced between the movable plate and the fixed plate；When the first port
When doing air inlet with one in the second port and acting another and do exhaust event, the movable plate from the higher-pressure region in seal chamber toward
Low-pressure area rotation in seal chamber.
In certain embodiments, the rotation-straight line conversion assembly is made of link mechanism.
In certain embodiments, the rotation-straight line conversion assembly just has a screw pair, which will be from activity
The output that is in line is converted in the rotation input of plate.
In certain embodiments, the movable plate passes through a permission along rotary shaft to the rotation between the screw pair
The driving member moved to direction.
The principle of the present invention is that draught head is converted into rotary motion using seal chamber, by rotation-straight line conversion assembly
Rotary motion is changed to linear motion, which, which acts on cutter chuck, changes gripping of the cutter chuck with respect to tapered sleeve
Amount, realizes the change of the tightness of cutter chuck, the especially present invention using in the preferred embodiment of screw pair, spiral it is self-locking
Effect can keep the clamping force of cutter chuck after aerodynamic force unloading, and direction rotates being used as power for screw pair need not be very big, be easy
It realizes that the elasticity of cutter chuck clamping force is adjusted with relatively small number of aerodynamic force, to saving gas consumption and guarantees what cutter clamped
It is self-locking to be all improved.

Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, embodiment will be enumerated below to this
The specific embodiment of invention elaborates.Specific reality to fully understand the present invention is elaborated in the following description
Apply example, still, the present invention can by be different from it is described below in a manner of implement, those skilled in the art can be without prejudice to this hair
Similar popularization is done in the case where bright intension.Therefore, the present invention is not limited by the specific embodiment of following discloses.
As shown in figure one to figure eight, the applicable cutter chuck of the present embodiment air-floating main shaft Pneumatic tool-changing apparatus is taper sleeve type knife
Have a collet, the taper sleeve type cutter chuck by outer surface at certain taper and be separated into three pieces sleeve clamping part 13 and can be with
The expansion set 50 of the outer surface cooperation of the clamping part 13 forms, and the mounting portion of cutter is placed in clamping part 13 and (does not draw cutter in figure).
When clamping part 13 moves right with respect to expansion set 50, clamping part 13 is pressed small, clamping force of the increase to cutter by expansion set 50；Conversely,
Reduce the clamping force to cutter.
In the present embodiment, the one end of pneumatic department 30 has a planar wall, opens up axis hole on the planar wall, one is fixed on
The fixed plate 32 of 30 ring wall of planar wall and pneumatic department, one forms rotary moveable with the air cavity lid 70 of above-mentioned end cooperation and the end
Air cavity 33.The movable plate 40 being placed in rotary moveable air cavity 33 is installed by shaft 20, can be made under the action of external pressure
The rotary motion of positive and negative both direction.The shaft 20 drives cutter chuck 10 to rotate by slide key, the spiral of cutter chuck 10
The screw pair 31 of pair 11 and pneumatic department 30 forms rotation-straight line conversion assembly, wherein shaft 20 and cutter chuck 10 constitute rotation
Swivel.Higher level's rotary motion is changed into linear motion and exported by the rotation-straight line conversion assembly gives junior's driving member --- this
It is connecting rod 12 in embodiment.Linear motion is transmitted on clamping part 13 by the connecting rod 12, drive clamping part make to the left or to
Right movement.
As Fig. 8 includes between fixed plate 32 and movable plate 40 when the exhaust of 72 the first air inlet of air inlet 71 of the second air inlet
The region of second air inlet 72 becomes higher-pressure region, and the region between fixed plate 32 and movable plate 40 comprising the first air inlet 71 becomes
Low-pressure area, then movable plate 40 and the counterclockwise rotation i.e. as shown in Figure 8 toward low-pressure area rotation from higher-pressure region.When movable plate 40 such as
When rotating counterclockwise shown in Fig. 8, the rotation-straight line conversion assembly being made of a pair of of screw pair becomes the rotation counterclockwise
It changes linear motion to the right into, increases clamping section 13 to the clamping force of cutter.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form.Appoint
What those skilled in the art, without deviating from the scope of the technical scheme of the present invention, all using the technology of the disclosure above
Content makes a variety of possible changes and modifications or equivalent example modified to equivalent change to technical solution of the present invention.Cause
